Hi,

I had this with Alex and Eleanor.
Alex's wasn't picked up until the day before he was born. When he was 3wks old we went back for a ultrasound on him and it should one larger than the other. We then went back for a test were they stick a tube inside and add fluid so they can tell if it is blocked. We went back every 6months until he was 18months old and they said that it is something he will always have but we still have to look out for UTI's. He was on antibiotitcs until he was 6months old just in case he got a UTI.

A couple of scans with Eleanor showed she had the same problem but hers went away before she was born.
